Abstract

Experimental reconstruction of an object shape from the near-field intensity of reflected or transmitted light is reported. The method of reconstruction is based on the direct numerical solution of the finite-difference representation of the paraxial irradiance-transport equation. Practical applications and limitations of the method are discussed.
